One workspace, fewer detours
From unfamiliar source to useful answer.
BigdataSight combines fast inspection, practical SQL, and controlled export without making a cloud upload the first step.
Query across sources
Keep stable source views in one workspace, write read-only SQL, compare results, and export the slice you need.
Reach remote data deliberately
Browse approved object and catalog paths, inspect metadata first, and avoid turning every remote preview into a full download.
Designed for deliberate analysisMetadata first.
Metadata first.
Rows when you need them.
Stay oriented when a source is wide, remote, or unfamiliar. BigdataSight keeps schema, query, result, and workspace context close together.

Questions, answered
Know what you are buying.
Is Viewer really free?
Yes. Viewer remains free without registration or a time limit. It supports local Parquet and CSV, single-source queries, two tabs, and current-page CSV export.
Is Pro a subscription?
No. Pro is a one-time purchase that permanently unlocks the currently delivered Pro capabilities. Current product updates are included.
Can Direct and App Store purchases be exchanged?
No. Both channels share the same core Viewer and Pro capabilities, but each uses its own purchase, restore, refund, and update system.
What happens when the Founder period ends?
Founder pricing is available for the first 90 calendar days after the coordinated public launch. Purchases made during that period keep Pro permanently.
